These nematodes were identified by an integrative approach combining morpho-anatomical and molecular data. We used two rRNA regions (D2-D3 expansion segments of the 28S, and ITS fragments), and the partial region of the cytochrome oxidase I gene (COI mtDNA) sequences. Hexametra angusticaecoides Chabaud & Brygoo, 1960 (Ascarididae) was morphologically characterized and illustrated using light and scanning electron microscopy. Bayesian inference (BI) and Maximum Likelihood (ML) phylogenetic trees for these genetic markers established relationships that highlight the importance of using molecular and phylogenetic data for accurate species identification within the genus Hexametra. Phylogenetic trees indicated that the Spanish isolates of H. angusticaecoides were clustered in a well-supported clade together with other isolates from Central Europe of the same species. Molecular phylogenetic findings also reflect that there was a higher intraspecific variation for ITS genetic markers at the intraspecific level. Phylogenetic results based on 28S rRNA suggest that Ascarididea was divided into three monophyletic major clades. To our knowledge, this is the first report of this species parasitizing bearded dragons, extending the host range of this species. These findings represent the first formal record of H. angusticaecoides in Spain.","PeriodicalId":54436,"journal":{"name":"Systematic Parasitology","volume":"102 1","pages":"6"},"PeriodicalIF":1.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142669787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diplomonorchis leiostomi has since been widely reported from the coastal Western Atlantic between Delaware Bay and southern Brazil. Until now, taxonomically verifiable DNA sequence data for D. leiostomi has been available from an individual worm collected from the northern Gulf of Mexico. We generated a partial sequence of the 28S rRNA gene from D. leiostomi from the spot croaker, Leiostomus xanthurus Lacepède (type-host) from Beaufort, North Carolina, USA (type-locality) that differed at 31 of 1,246 bases from the available 28S sequence. This prompted a reevaluation of Diplomonorchis spp. identities from the northern Gulf of Mexico. We found D. leiostomi and D. micropogoni distinguishable by testes shape and size, and to a lesser degree by relative caecal length. Museum specimens of D. leiostomi, identified from the Gulf of Mexico represent a species complex containing D. leiostomi, D. cf. micropogoni and, a new species of Diplomonorchis. The sequences previously identified as D. leiostomi in GenBank (AY222137 & AY222252) are herein identified as D. cf. micropogoni. The new species is described from newly collected material herein. Phylogenetic analysis of 28S rRNA sequences from the species complex plus 46 species from the Monorchioidea Odhner, 1911 indicated all three Diplomonorchis spp. are closely related and form a clade with some species of Lasiotocus Looss, 1907.

The generic diagnosis of Sudarikovina is amended. The main corrections for diagnostic characters at the generic level include: irregularly-spaced transverse anastomoses of ventral osmoregulatory canals; presence of both specimens with dextral genital pores and specimens with sinistral genital pores; vagina clearly covered externally by a dense layer of intensely-stained cells; young uterus reticulate and fully-developed uterus with a labyrinthine structure. The previously proposed generic character of a minimum number of testes per proglottis of species of Sudarikovina is reduced to 3. The genus Paraoligorchis is recognized as a junior synonym of Sudarikovina. For the type species of Paraoligorchis, P. taterae Wason et Johnson, 1977, the replacement name Sudarikovina wasojohni nom. nov. is proposed, thus resolving the secondary homonymy of the transferred species and its senior homonym S. taterae Hunkeler, 1972. The validity of the tribe Sudarikovinini sensu Spassky (1991), to which Paraoligorchis and Sudarikovina had been attributed, cannot be resolved due the lack of molecular data. The cestode specimens from Shaw's jird, Meriones (Pallasiomys) shawi (Duvernoy) from Algeria and Tunisia, initially designated as Hymenolepis sp. by Joyeux (1923) and Hymenolepis procera Janicki, 1904 by Joyeux & Foley (1930), represent undescribed species of Sudarikovina, which are described in this study as Sudarikovina pentatesticulata sp. n. and S. tetratesticulata sp. n., respectively. The main diagnostic characters of the two new species, which distinguish them from their congeners, are the number and the size of the testes.","PeriodicalId":54436,"journal":{"name":"Systematic Parasitology","volume":"102 1","pages":"3"},"PeriodicalIF":1.0,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142632490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
